The handle tube of the GN 333 tubular handles can be screwed to the handle bases without further machining or processing, allowing special lengths to be realised easily. A typical application area for tubular handles GN 333 are double-winged doors at machines or devices. Further handle legs can be added for very long tubular handles. Individual handle legs for tubular handles Ø 28 (type A) are available under GN 333.8.
